Method and device for calibrating battery external inspection camera

Abstract

A method for calibrating a battery exterior inspection camera performed by at least one processor is provided. The method includes generating a reference image by photographing a color checker including a plurality of color regions with a reference camera, generating a calibration target image by photographing the color checker with a calibration target camera, extracting a first red (R) value, a first green (G) value, and a first blue (B) value corresponding to the plurality of color regions of the color checker from the reference image, extracting a second R value, a second G value, and a second B value corresponding to the plurality of color regions from the calibration target image, and generating a look-up table for each RGB channel based on the extracted first R value, the first G value, the first B value, the second R value, the second G value, and the second B value.
